When I got home from work today I let Oreo inside as usual. But as I fed him, I noticed that he had a gaping tear on the underside of his tail. Errrr... not a good thing! So I called the vet, got the carrier down and bundled Oreo off to the vet. We'll have to wait until tomorrow afternoon to see how he goes.
And yes, that is his carrier- they didn't have a blue one at the time so he's stuck with bright magenta!
